Oh yes, I live in switzerland. But I come from the northsea coast in germany.
The boat shall be used for daysailing here on the swiss lakes. We have the Lake Thun infront of the door and with the thermical conditions we get winds between 2 and around 5 Beaufort in summer. Sometimes storm can come quickly....There are some more lakes and the lake geneve is very near (100km away) and a very lovely place.
I also want to go to the northsea coast with that boat for holidays. There are the "frisian islands" what is a wonderful place to sail with many islands like a pearl necklace near the coast. It ranges from the west of the netherlands with the island Texel and reaches up to nearly denmark with the island Sylt. It has shallow water, but the conditions are not easy. For big ships its known as one of the most dangerous waterways of the world. Maybe you know it as "german bight". Behind the islands there is a deep water way for the big ships going for example to Hamburg and Bremerhaven. The most german cars get shipped from there into the world too.
The other place is the baltic sea. I would like to sail from the german coast near Kiel or Lübeck to the danish islands and in the flat waters from east germany to poland.
The third place to go for me is the coast of the mediterran sea from france (Marseille) up to italy croatia and else.
Yoe see that the boat will travel a lot. So trailering is a big point. The ways to germany, netherlands and croatia are up to 1000km oneway. Im not willing to have a trailerweight more than 1500kg. The trailer can be up to 300kg, so the complete boat, ready for holidays shouldnt be more than 1200kg. Of course we can store things in the car too....;-)
I owned a 24ft plywood boat for many years. But she had a deep keel with draft from 1,60m. She stood 3,60m with the trailer and was going up to 2000kg trailerweight. That was to much for me and the boat was 40 years and needed a complete refit. So I sold her and now we are looking to build a new one...
